=head1 NAME

B<gpt_convert_xml> - Converts original XML package files to the new XML
format. 

=head1 SYNOPSIS

gpt_convert_xml <XML Package Data File Name> 

=head1 DESCRIPTION

B<gpt_convert_xml> will take a GPT version 1.0 or 2.0 XML packaging script
and convert it to the XML format that will be used in future GPT releases. 
I<XML Package Data File Name> is the name of the GPT packaging file that 
will be converted.  This name will also be used in the new GPT XML file
that is created.  The new file will have the form: B<CONV)>I<XML Package Data 
File Name>.

=head1 Description of the Files that B<gpt_convert_xml> Creates

=over 4

=item B<CONV_[XML Package Data]> B<gpt_convert_xml> creates this file from
the contents of the original package data file.  The file will be layed out
using the new XML file lay out as specified by the GPT DTD file.

=head1 Post B<gpt_convert_xml> Tasks (What is Left to the Developer)

=back

=item B<gpt_convert_xml> does not do everything that is needed in order to
fully convert the XML file.  Some tasks need a developer's touch.  Here is a 
checklist of tasks that may need to be done by hand:

=over 4

=item  B<ContactInfo> needs to be added.  This is a new field used
to hold information on the package creator.  The tags: I<ContactName> and
I<ContactEmail>, should be filled in.

=item B<PackageDocs> needs to be added.  This is a new field used to
hold imformation about documents related to the package.  The tags:
I<PackageDocsDesc> and I<PackageDocsURL> need to be filled in.  The
description should explain what the document is and the URL should hold
the location of the document.
